Abstract

A parametrization of the real photon structure function (Formula presented) in the low (Formula presented) low x region is formulated. It includes both the vector meson dominance (VMD) and the QCD components, the latter suitably extrapolated to the low (Formula presented) region and based on arbitrary parton distributions in the photon. The parametrization used together with the Gluck, Reya, and Vogt (GRV) and Gluck, Reya, and Schienbein (GRS) parton densities describes reasonably well the existing high energy data on (Formula presented) (Formula presented) and the low (Formula presented) data on (Formula presented) Predictions for (Formula presented) and for (Formula presented) for energies which may become accessible in future linear colliders are also given.
